Someone help please, this is due in 10 minutes and I dont know the answer.

Step-by-step explanation:

Rate of change = the difference in y/the difference in x.

20 - 6.50/4 - 1 = 13.5/3 = 4.5/1

24.5 - 20/5 - 4 = 4.5/1

33.5 - 24.5/7 - 5 = 9/2 = 4.5/1

The rate of change is 4.5.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
